Sea Level Rise and Anomalies in Hong Kong because of Climate Change by City-Tech Blogger Lok Ting Wong

In this essay, I will talking about the sea level rise and anomalies in Hong Kong because of climate change. Climate change is the biggest problem in Hong Kong. According to the report from Hong Kong Observatory, the sea level is rising very rapidly because of the temperature increase, which is caused by the greenhouse gases. This makes the weather and environment become anomalies. The high temperature melts land ice and snow into the ocean causing an increase in average sea levels causing the thermal expansion of seawater. Figure 1 below shows the annual mean sea level in Hong Kong. Based on the data, we can see the average sea level increase by about 3 cm every ten years. It means the threat of storm surges brought by tropical cyclones will also increase in Hong Kong (see Figure 2). The sea level rise could pose serious problems for the bay area in Hong Kong, especially at lower altitudes. Therefore, Hong Kong government and its people should consider how to face climate change to slow the sea level rise.

The earth is getting warmer and warmer each year, and the main culprit is the human activity.  People heavily rely on the burning of fossil fuels to produce energy for human daily use, but carbon dioxide is released during production adding to the greenhouse gases in the atmosphere, trapping heat in and increasing the temperature. Therefore, hot days and rainfalls will become more frequent in the future as will cold days become less frequent. The solution of climate change and sea level rise in Hong Kong could come in many forms: first of all, people should plant more and more trees in order to reduce the carbon dioxide released in the air because plants and trees absorb CO2. It is the most effective way to prevent climate change or slow down the impacts before they become worse. Public transportation is a viable alternative instead of the personal car, or walking is even more preferable. These are ways to possibly prevent  climate change or global warming in the world, not only Hong Kong.  Finally, people should do whatever they can to save the environment and the future of the next generations. The earth will not recover by itself, we need to do something to save it. Don’t be wait, we can save the world together.
